AB = √ ( -2-2) ^2 + 0
AB = √16 = 4 units
BC = AC = AB = 2 units
AC = √ (x-2) ^2 + ( y-0 ) ^2
AC =√ x^2 -4x + 4 + y^2 ............( EQ 1)
BC = √ ( X+2) ^2 + (y-0) ^2
BC = √ x^2 + 4x + 4 + y ^2 .........EQ 2
from equation 1 and 2
8 X = 0
X = 0
now AC = 2 units
so√ x^2 -4x + 4 + y ^2 = 4
squaring both sides
x^2 -4 X +4 + y ^2 = 16
put X = 0
y ^2 = 16
y = +- 4
so coordinates may be either ( 0,4) or (0,-4)
